If you are planning to drive from Chennai to Bangalore or the other way, please take the Golden Quadrilateral.
Usually, my wife and I drive take that road. But a friend of mine this time suggested that we take the Old Madras Road. Hoping to beat the traffic on Hosur Road from Electronic City to Silk Board flyover, while coming from Bangalore we took Old Madras Road. I was also told that the drive is scenic. Scenic, it could have been, but I had to concentrate on the road all time time. First of all, unlike Golden Quadrilateral, which is four lane with a median, Old Madras Rd is just a two lane Highway with no median. Two, the traffic is heavy.
If you want a smooth faster drive, please stick to Gold Quadrilateral.
